As I haven't yet used one of these exotic beasts, I can't be sure - but I believe that networking is the same as XP. click here for a fix. Note that, to the best of my knowledge, you cannot setup a laptop to work with 2 separate DHCP servers.
The trick is to set it up to use one - then, when it can't find that one (as it is on the 'other' network), it defaults to a pre-defined IP address. The 'other' network's router/server must be setup to automatically allow the pre-defined IP address.
